Chemotherapy is often given as a combination of drugs. Combinations usually work better than single drugs because different drugs kill cancer cells in different ways.

  • Infection

  • Mouth Sores

  • Nausea & Vomiting

  • Appetite Loss

  • Alopecia or Hair Loss

What side effects did you experience while on this medication?

Hi, I'm souplady

AC was tougher than the Taxol for me – I would feel nauseated for only 2-3 days, but felt tired and “crummy”, which would last until 2-3 days before the next treatment. Taxol was pretty easy, compared to AC – after a few weeks I started having back pain the night of treatment, which seemed to get worse with time – but only lasted for the night. I learned to come home from treatment and take a nap (assisted by the Benadryl given prior to treatment), then stay up with the family to watch the baseball game (2001 – the Mariner’s “dream” season!). I wouldn’t get much sleep that night because of the back pain, but had the weekend to recover. I was able to work the entire time, just cut back the hours a bit (probably = to .8 FTE). Good luck!
